Electronic Throttle Control System (ETCS)

[ecu_designer]

The Electronic Throttle Control System (ETCS) / Throttle-By-Wire (TBW) / Drive-By-Wire (DBW) all are same species. Nowadays almost all latest A/T vehicles are outfitted with DBW technology. DBW is a complex Throttle Control System as compared to traditional Drive-By-Cable Mechanical Throttle Mechanism. It provides a great freedom to Engine Management System. A State-of-the-Art discrete PID controller is pertained for throttle servo mechanism. The redundancy incorporated in the system for safety reason and the deficiency of Idle Air Control (IAC) valve makes the thing more exigent.

Say Good Bye to Old Mechanical Cable Throttles. Its fairly possible to replace traditional mechanical throttle with electronic throttle body. The DBW requires an additional DBW Controller / Module in case of an ordinary ECU with no DBW capability. The IAC signal input provision in DBW Module allows the existing ECU to stabilize the Engine Idling / deceleration RPM.

DBW can be used for subsequent applications i.e. Cruise Control, Engine RPM Limiter to prolong life, Vehicle Speed Limiter, Auto Transmission shift jerk suppression, Electronic RPM Governor for Gasoline / CNG Generators etc

nice work!
may i ask how did you implement a PID on it?

Sorry to disturb you mate

Exclude FLY BY WIRE from your description. i hope you understand

FLY by wire has nothing to do with the throttle system of an AIRCRAFT.

Seems this thread will turn into brother of that recently famous Fuel reducer Kit..

Sir this thing has nothing to do with fuel reduction thingy, its just a home made System nothing else

u can see the demonstration video

I dont drive too fast, I just fly too low

All technical details are there, no magical stuff, just a DIY project

I hope Technical Engine guys will get my point

i was watching this video of yours:
OBD2 Diagnostic Tool Project using ATMEGA32 - Video Dailymotion

and i want to know which graphic lcd did you use?

@OP

Flying too low ?

Remember not to hit a WAPDA pole in your way

i was watching this video of yours:

and i want to know which graphic lcd did you use?

Its "128x64 Graphics LCD"

does the new corolla have a drive by wire system....? if so i loath it... it has the most stupid throttle response.. the engine is a whole second slower than my foot motion...

[HellsGuardian]

Its "128x64 Graphics LCD"

is it available locally? i want to buy one such LCD and wondering if you can guide me

Nice Work Done ... Thumbs Up

Let Me Tell Everyone Here That This Guy Implement Things For DIY And Learning Purpose And Comes Out With Genuine Output...Either He Fails Or Succeed.....!!

Yes It Does.....I Have Driven JDM Corolla With DBW ANd It Was Smooth As Butter......CVT Adding More Comfy.....!!

In Severe Rain Conditions.....It SHould Worry You

[nfssaad]

i drove a 2011 gli local corolla... manual...

i hated it... compared to my 96 civic its really crap.

it was driven quite a lot... sort of rental... the engine responded 1 sec after i put my foot down. and when i stepped on the brakes the engine was still revving up..

Dear Hameed01 Sahab,

How did you come to the conclusion that Auto Transmission Shift Jerk can be minimized with this??

This is an OBD2 recorded data of a Honda City 2009 (DBW engine) with an automatic transmission

As depicted in the figure, when the gear changes, the throttle position (dotted red) is closed and opened back again. While the pedle position remains steady. Ideally it is supposed to reduce shift jerk.

First off, your attachment isnt displaying

Secondly, if you want I can attach the image for you along with the table logs from which the graph was generated.

As much as I appreciate your interest and efforts in vehicle electronics, its sad that you actually stole an idea and coupled it as part of marketing your ETCS.

Not even that, you used the exact same words from my email to you...to reply to my question above.

Nice!!!!

Its not like Winklevoss Brothers against Mark Z, but then again, the society deserves the truth.

For reference.

Yup Mr Nauman i know u emailed me & u r facing a jerk issue.

Dude i am not marketing any thing over here, & i have not solved that shift jerk problem. i said its possible to nullify or minimize that jerk issue. if u want i can post ur complete email over here.
